VILLIAM H. SAVYER, OF PROVIDENCE, RHODE ISLAND@ WIRE-DRAWING MACHINE.

SPECIFICATION forming part of Letters Patent No. 367,667, dated August 2, 1887.

Application tiled June 10, 1886.

To @ZZ whom, it iii/ay concern.-

Beitknown that I, WILLTAM H. SAWYER, a citizen of the United States, residing at Providence, in the county of Providence and State of Rhode Island, have invented certain new and useful Improvements in fire-Drawing Benches; and I do declare the following to be a ful-l, clear, and exact description of the invention, such as will enable others skilled in the art to which it appertains to make and use the same, referencebeing had tothe accompanying drawings, and to the letters and figures of reference marked thereon, which form a part of this specification.

This invention relates to a multiple wiredrawing bench, its .object being to enable a large number of wire-drawing operations to be carried on at the same time by mechanism deriving motion from a common prime motor and in position to be conveniently superintended by a small number of attendants, my invention being especially designed for the manufacture of wire on a large scale.

In the accompanying drawings, Figure l represents a perspective view of a wire-drawing bench constructed according to my invention, the view being .taken on the side of the bench on which the drawing-reels are located. Fig. 2 is a similar view on the sidey of the bench upon which the delivery-reels are located. Fig. 3 is an end view of the bench. Fig. 4t is a vertical section showing the mech anism by which the traversing-i`ran1e is operated. Fig. 5 is aview of one of the reels; and Fig. 6 is a vertical transverse section of a modified form of my invention.

Similar letters of reference occurring` on the several igures indicate like parts.

The letter A indicates the table which su pports the mechanism, and should be strongly constructed, so as to support considerable weight and strain. Secured to one edge of the bench are a series of projecting brackets, B, each having two arms provided with bearings for th@ spindles (i, which receive the drawing-reels G, said spindles projecting to one side of the brackets and provided with a shoulder, c, against which theone side of said drawing-reels abut when in position upon the spindles, the outer ends of which are preferably screw-threaded to receive a suitable nut Serial No. 201,749. (No model.)

to hold the reel in position thereon. Upon the spindle between its bearings is secured a belt-pulley, D, from which a belt passes to a similar pulley, D, iixcd upon a driving-shaft, E, mounted in bearings below said shaft, the outer end of which is provided with a beltwheel, E', to receive motion from a belt connected with any suitable motor. A belt-tightening wheel, F, is provided foreach belt, said tighteningwhecl being carried by an arm, F', having one end pivoted under the table, the outer portion of said arm being supported by a longitudinal bar, f, when the tighteningwheel is not in use. Normally the belts run free and loose and will not transmit motion to the spindles unless the tightening-wheels are laid against them, as shown in Figs. l and 4.

The spindles C when in use carry the d-rawing-reels G. The irstvspindle in the series at the near end of the table is left withoutarecl, in orderto show its construction; buttheother spindles are provided ,with reels, as when in use. Each rcel consists of a cylindrical drum or shell, y, with outwardly-projecting ianges at its edges, and inside of this shell is a wooden centerpiece or head, g', composed of two parts, which are inserted from opposite sides and drawn together by bolts gl, these two parts being slightly tapered, so that they will be wedged tightly in the shell. Through the center of the center pieces is iirml y fixed a tubular shaft, g, projecting on each side of the center pieces and having a bore of` proper diameter to lit snugly on the spindles C. Vhen this tubular shaft is placed upon one of the spindles,its inner end rests against the shoulder c, and a suitable nut is screwed up against its outer end to clamp it tightly, so that the -reel will be carried around when the spindle is rotated. Near the inner edge of one ofthe danges of the reel is a small hole, 71., through `which the end of the wire to be drawn is passed and knotted on the outside to make it fast.

In the opposite edge ot' thc bench from the drawing-reels are a series of recesses, cach of which is directly opposite theV brackets B, as shown in Fig. 2. Projecting from the top of the table, near the edges of each recess, is a pair of pins, i, atsueh distances apart as to receive loosely between them the ends of the tubular shaft g* of a delivery-reel. rEhe letter IOO 'ingshaft E.

Ii designates the traversiugframe, which carries the dies L, through which the wires are to be drawn. I This travcrsing-frameis composed of two sections, as shown, each section being composed of two parallel bars, 7., 7c, in one of which, next to the spindles, the dies L are arranged, and in the other are formed slits Z, as

shown in Fig. 2, which serve as guides to direct the wire in a straight line with the dies. The bars 7c 7s are provided Yat intervals with longitudinal slots k 7.7, through which horizontal pins project from stout standards M, firmly secured to the top of the table, these slots allowing the longitudinal slowly-reciproeating motion ofthe frame.

At each end ofthe table is mounted a pulley, N, over which runs a cord attached to the inner end of the traversing-frame sections, after passing over an intermediate pulley bcneath the bench, as shown in dotted lines in Fig. 2, while its other end depends and has connected to it a weight snfiieiently heavy to force the framesection endwise inwardly against the heart-shaped cam O.

At about the middle of the table is mounted a transverse shaft, O', which carries at one end a heart-shaped cam, O, against the periphery ot which the inner ends ofthe traversi 11g-frame sections are forced bythe weights, these ends of the frame-sectiens being provided with small f rietion-rollers, which bear directly against the periphery o-f the said cam. Upon the opposite end of the shaft O is a bevel gear-wheel, O2, which meshes with a similar wheel O, fixed upon the upper end of a vertical shaft, O, upon the lower end of which is another bevel gear-wheel, O5, meshing with a similar wheel, O, on a shaft, O7, mounted longitudinally under the tableand carrying a beveled gear-wheel, O8, which meshes with a pinion, O", upon the d riv- The gear-wheel O* is very much larger than the pinion O, and when said pinion is rotated a slow motion is transmitted through the gears and shafts j ust enumerated to the heart-shaped cam, which in turning drives one of the traversing-frame sections slowly outward and allows the other to be driven slowly inward by its weighted cord.

A series ol" blocks, I, are hinged to the top of the table and arranged to bear against the peripheries of the flanges ot' the delivery-reels mounted at the recessed side ofthe table, these blocks being provided with cleats or shelves p to support weights to cause the blocks to inlpinge against the reels with sufficient force to prevent them from turning too freely, the object of these blocks being to keep the wires tant while being drawn from the reels to the dies.

Above the top ofthe table is supported a longitudinal trough, Q, between the two bars ofthe traversi11g-frame, but at a slightly-lower level. This trough or pan is closed at the top, except for certain oblong openings (l, which are arranged under the paths of the wires. This trough or pau is to hold oil or other material dies.

with which the wires are to be lubricated as they pass to the dies; and in order to apply such material to the wires I mount upon the Vtable a longitudinal rockshaft, It, provided with arms It', bent at right angles at their outer ends, these arms It being of such length that when the shaft It is turned in one direction their bent ends will be dipped into the lubricating material through the openings q, and when the shaft is turped in the other direction these bent ends will be raised and touch the wires above, imparting to each a Vsmall portionfof the Vlubricating material with which said bent ends become covered. In order to give the arms Ra proper rising and falling motion, I tix a radial arm, R2, to the shaft It, and to the outer end of this radial arm I connect the upper end of a rod, It, the lower end ot' which is connected with the hub of belt--wheel E on the main shaft E. Directly under each die is a funnel, S, havingits spout extended downward through an opening in the table, in proper position to discharge int-o an inclined pipe, S', arranged undersaid table and having under one end a receptacle, S2, to receive whatever may iiow from said pipe. Along the top of the table, directly behind pans Q, runs a steampipe, T, which at one end of the table is provided with suitable means for connection to a steam-supply pipe, and its other end may lead ot'f: to any desired point to discharge; or said pipe maybe arranged for connection in any well-known manner to secure through it a continuous circulation of steam, its object being to keep the lubricating material at a. proper consistency on the wires. The operation of the invention above de; scribed is as follows: A rod of iron or other metal to be reduced to wire is wound upon one of the reels G, which is then. placd in one ot' the recesses in the edge of the table, with the ends of its tubular shaft between the pins t' z' on each side of the recess. of the rod is then drawn through the guide-slit and die in the traversing-frame to a reel fixed upon a spindle on the opposite side ofthe table, and is secured to said reel by being passed through the hole hand knotted on the outside. Brake-block Il is then laid against the periphery of the flanges of the reel from which the wire is to be drawn. rlhe trough or pan Q, is properly filled with lubricating material, and if the weather is cold steam is turned on through the pipe T. Reels supplied with rods to be drawn may be arranged in all the recesses of the table, and have their rods led through the dies to reels or opposite spindles, as already described. The belt' tightening wheels are laid against the belts, and motion being then communicated t0 the main shaft E by a belt passing around the rcel E', the reels on the spindles will be rotated in the direction to draw the rods oft' the reels on the opposite side ofthe table, reducing said rods in the ordinary manner, according to the size of the The outer end Vhile the wire is being drawn the- ICO traversing-frame K is moved slowly lengthwise by the action of the heart-wheel O, as heretofore explained, so' that the wire is wound inV uniform layers upon the drawing-reels. Meanwhile a rocking motion is communicated to the shaft It, through the connection already described, and the bent ends of the arms R are alternately dipped into the lubricating material and raised to touch the wires and give them a suitable lubrication. As the wires are then drawn through the dies a portion ofthe lubricating material is scraped off and falls into the fuunels S, being directed by the spouts of the funnels to the inclined pipe under the table, by which the dripping material is conducted to the receptacle arranged to receive it. W'hen the drawing-reels are filled withwire and the reels on the opposite side of' the t-able emptied, the iilled reels may be removed from theV spindles and the empty reels removed from the recesses and placed upon the spindles, being themselves replaced by the filled reels,from which the wires may be drawn in the same manner as already described, but each wire beingdrawn through a smaller die than that through which it iirst passed, this interchange of filled and empty reels being conti nued and successively smaller dies used until the wires are reduced to the desired size. The dies may be successively removed from the traversing-frame and replaced by smaller ones, or they may be arranged to successively decrease in size from one end of the traversing-frame to the other, and the reels, when interchanged, may be shifted suecessively to smaller dies, so that while at one end of the bench the first drawing of a rod is taking place, at the other end, or at some intermediate position, the last reduction is being given to a wire which has been passed through a series ot'idies. 'Ihe'process of drawing may be commenced at either of the spindles, or at two or more spindles, if desired, simultaneously, for different kinds of wires from those being commenced or in process of completion at other spindles.

At any time when it is desired to stop the rotation of any of the spindles for any purpose, it may be done by shifting the tightening-wheel from its belt, the operation of the other-spindles continuing without interruption.

Fig. (i is a vertical transverse section of a modified form of myinvention, being a double multiple drawing-bench, with drawing-spindles at both edges and employing two travers ing-frames, the iilled reels from which the gether, except that a single driving-shaft is used with suitable belts for driving both sets of spindles, and with duplicate sc ts of gearing and shafts to operate two heart-wheels for iniparting thexproper motion to both traversing frames.

As another modification, I may provide each of the traversing-frames with two sets of dies, opposite each other and supported by vthe bars of each frame-that is, instead of the guide-slits in the inner bars, I may use dies of larger gage than those in the bars next to the spindles, so that any or all of the wires may provided with beltpulleys,.a common driv-` ing-shaft provided with belt-pulleys, and the normally-loose belts, of the shiftable belttightening wheels, substantially as described, whereby motion is transmitted to each of the drawing-reels independently. and the rotation of any of said reels may be stopped without interrupting the others, substantially as described.
